Using genetic data to understand past human interactions with biodiversity

Te Papa researchers: Lara Shepherd and Isaac Te Awa

This research uses genetic techniques to provide insight into New Zealand’s cultural past. Our research findings provide new knowledge on interactions between Māori iwi by determining the translocation pathways of cultivated plant species.

We are also using DNA to examine the relationships between weaving cultivars of harakeke and distinguish between plant species used to make tapa (barkcloth) in the Pacific region.
